Default How much radiator will I need?

I have a second generation Rotrex kit to install. (the one with intercooler). I'm expecting to be under 200 WHP with my otherwise stock engine (2 1/2" exhaust, stock header). Do I need to go with an FM or TSE radiator or will a 55mm Koyo suffice. I am in the Midwest so not too may 100 degree days here. Car will see many track days with 1/2 hour sessions. I see Emilio is offering a new radiator also (looks like the FM)

I'm thinking I should also get an oil cooler. Any suggestions?

Thanks!

Do a coolant reroute. Add an oil cooler. Add standalone water and oil temp gauges where they are visible. Make sure your air ducting (OEM or DIY) is in excellent condition.

Start with a stock radiator and go from there. If you need more, you'll soon know.

I track, in TX in August, with an OEM radiator and the above mods. Only difference is I don't run an intercooler. With an intercooler, you may need more, but I wouldn't spend the money up front.

I agree with the reroute and oil cooler. I also agree with the 949Racing crossflow radiator. Ducting everything tightly will be the key to your success.
